Abstract

A method of estimating a property of interest downhole according to one aspect of the disclosure may include continuously receiving a core drilled from a formation into an open end of a chamber while removing the core distal from the open end of the chamber; obtaining a measurement relating to property of interest of the core using at least one sensor; and estimating the property of interest of the core using the obtained measurement.
